METHOD FOR CONSTRUCTING CONCRETE BUILDINGS.

Specification of Letters Patent.

Application led August 2, 1909. Serial No. 510,768.

Patented Aug. 13, 1912.

To all whom it may concern.'

Be it known that I, AUGUST RAsMUs BALTZER, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Methods for Constructing Concrete Buildings, of which the following is a specification.

lThis invention relates to an improved method for 'constructing buildings of reinforced concrete.

One of the objects of the invention is to provide a rolling wall supporting structure which may serve, either by gravity, or by the application of power, to swing the wall from a substantially horizontal position into a vert-ical posit-ion and on to the foundation therefor.

The invention will be more fully described in connection with the accompanying drawing and will be more particularly pointed'out and ascertained in and by the ap ended claims.

n the drawing :-Figure 1 is a view partly in section of a wall and foundation with the improved device of my invention shown in the position which it would assume when the wall is being placed in position. Fig. 2 is a similar View showing the device of my invention in the position which it assumes when the'wall isbeing formed and permitted to set. Fig. 3 is a rear elevation with the parts in the position shown in Fig. 2. Fig. 4 is a diagrammatic view of a modified form of the invention in which power is applied to swing the wallfrom a forming or horizontal position into a vertical position. Fig. 5 is a sectional view on line 5--5 of Fig. 1.

Like characters of reference designate similar parts throughout the diiferent' figures of the drawing.

As shown a support or foundation is indicated at 1, the cellar at 2, and the wall at 3, and the wall of an adjacent building at. 4.

A supporting' or track structure 5 is disposed in the cellar 2 and includes uprights 6 and 7 upon which a track bar or member 8 is disposed. In the form shown the upright 7 is somewhat higher than the upright 6 so as to incline the track support 8. In the of these segmental supporting structures" will be arranged in suitable parallel relation spaced suitable distances apart in accordance with the length of the Wall, as clearly shown in Fig. 3. Each of said rolling structures may be provided with a trussed member 13, and these trussed members 13 may-be provided with extensions 14, detachably secured thereto, as at 15. A plurality of different lengths of extensions 14 may be provided to accommodate walls of different heights.

The trussed member 13 may be connected by transversely disposed members, in the form of channel-irons 16, on which a bedstructure of boards or the like 17, may be disposed, to receive the concrete or other material of which the wall is to be formed. The boards 17 constitute the concrete bed and may be provided with end boards 18, one only being shown, which is adapted to be held in place during formation of the wall by a removable foot portion 19.

A convenient means for anchoring the boards 17 and channels 16 to the members 13 may consist of bolts 20, extending through the members 13, and channels 16, and boards 17 into the wall 3, and the nuts 21 embedded in the wall 3 as shown in Fig. 1. After the wall is positioned on to the foundation the heads 22 of the bolts 20 may be turned to disengage the bolts from the nuts 21, thereby leaving the nuts in the wall, and permitting the struct-ure to be rolled away from engagement with the wall.

The several structures 10 may be suitably connected as indicated at 23, so as to form a unitary structure.

It will be obvious that when the rack 9 is set at an incline the center of gravity will be so disposed as to cause the rolling structure l() to normally seek the position shown in Fig. 1, and position the wall by gravity on to lts foundation. However if the upper portion of the wall projects above or beyond the structures 10, ata, a sufficient distance to prevent the structures 10 from moving by gravity to tbe position shown in Fig. 1,

means may be provided inthe form of weights 24, to insure movement of the struc-- 'I ing movement of the structures 10, when the wall is being positioned, and said means is herein diagrammatically indicated in the form of a restraining cable 26, which ma be connected at 27, and controlled by a windlass 28, or other suitable device in any con- ,ivenientgmannen A modified. forni" of the invention is shown in Fig. It, diagrammatically, wherein the rolling bed supporting structure 29 1s disposed upon a horizontal y arranged track structure 30. In order to roll the structure 29 into a position to place the wall upon a foundation, power may be applied to a device 31.

It will be seen that my improved method and apparatus may be used to great advantage in positioning a Wall upon a foundation which is closely adjacent toI a finished structure, inI view of the fact that a wall may be positioned upon its foundation without being projected upon the vertical plane thereof outwardly, and it will also be apparent that even thoughv the wall were in practical contact with an adjacent finished structure it could be positioned upon its foundation without any 'interference therewith.

It will be further obvious that in view of the fact that the wall is supported from its inner surface, in the recess of formatin any desired exterior nish may be carried out in the process of forming the wall.

)It Will be further obvious that the wall may be (positioned wholly by gravity thereby avoi ing the necessity of providing any form of operating means.

In order to accurately position the wall 3 on the foundation 1 adjusting means may be provided for the rolling or arcuate structure 10. In the embodiment shown the racks 9 are mounted on anti-friction rollers 32 dis- -is pivoted to the standard 7 andeinbraces the lower end of the lever 9 and carries an In accordance with my invention, the wall is progressively and-bodily shifted toward a predetermined support or foundation on constantly changing points or bases of su port, into a vertical position and onto t e support or foundation.

I claim 1. 'A method of constructing concrete buildings' which consists in supporting a concrete Wall in a suitable position inside the foundation during formation, and in placing said wall upon a foundation by gravity Without projecting the wall outside the vertical plane of said foundation.

2. A method of constructing concrete walls which consists in supporting and forming in a substantially horizontal position a complete concrete wall of the desired height, and in progressively and bodily shifting all portions of the Wall simultaneously toward a predetermined support and toward and into a vertical position and in finally posi-l tioning said wall in a permanent position on such support at the completion of such shifting movement and when the wall has assumed a vertical position.

3. A method of constructing concrete walls which consists in supporting and forming in a substantially horizontal position, in a mold body, a concrete Wall, and in progressively and bodilyshifting said mold body and the Wall 011 diderent and changing bases of support toward and into a permanent vertical position.

4. A method of constructing concrete walls= V placing the wall upon such foundation at the completion of such shifting movement.4

5. A method of constructing concrete walls which consists in supporting and forming in a substantially` horizontal position a concrete wall ofthe desired height, and in progressivelyand bodily shifting all portions of the wall simultaneously toward a vertical position on to a predetermined support and restricting the complete shifting cycle of the Wall to a predetermined course of movement from the starting to the final positioning of the wall.

6. Amethod of constructing concrete walls gressively and bodily shifting said mold with its wall on different bases of support gradually approaching a foundation, and

'with the entire shifting operation restricted to a predetermined direction andcharacter of movement toward a vertical position, and in finally and permanently placing said wall upon the foundation at the completion of such shifting movement.

7. The method of making concrete walls for buildings which consists informing a Wall in a mold disposed in a substantially horizontal position to properly set the concrete, land in shifting the Wall and mold through a predetermined cycle of movement consisting in simultaneously moving all parts of the mold and wall bodily in a substantially horizontal direction, and in causing all of the parts of the Wall and'mold to simultaneously and gradually assume a vertical position during such bodily horizontal movement to position the Wall' upon the foundation.

8. The method of. making and erecting concrete Walls for buildings which consists of forming a wall in a mold disposed in a substantially horizontal. position to pro erly set the concrete, with that portion oi) the mold that carries the bottom edge of the Wall located out of contact with the foundation, and in then bodily moving the mold and. the Wall upon constantly changing points of support toward said foundation and bringing said wall to a vertical position and depositing said wall upon said foundation.

9. The method of making and erecting concrete walls for buildings which consists of forming a wall in a mold disposed in a substantially horizontal position and in then bodily moving the mold and the Wall upon constantly changing points of support to- Ward a previously 'constructed ermanent foundation andbringin said Wal to a vertical position and depositing said Wall upon said foundation, said wall being positively guided during such movement to properly position it in a predetermined relation upon the foundation.

10. The method of making and erecting concrete Walls for buildings which consists of forming a Wall in a mold disposed in a substantially horizontal position, and Iin then bodily moving the mold and the Wall upon constantly changing points of support toward a previously constructed ermanent foundation and bringing said Wal to a vertical position and depositing said wall'upon said foundation, said Wall being positively guided during such movement by means located entirely below the outer face of the Wall to properly position it in predetermined relation upon t e foundation.
